Critical (9.9) in gogs gogs. EPSS 7.7% chance of exploitation in the next 30 days. Fixed in gogs.io/gogs 0.13.1.
The built-in SSH server of Gogs through 0.13.0 allows argument injection in internal/ssh/ssh.go, leading to remote code execution. Authenticated attackers can exploit this by opening an SSH connection and sending a malicious --split-string env request if the built-in SSH server is activated. Windows installations are unaffected.
